Do not click links or open attachments unless you verify. Send all suspicious email as an attachment to report.spam@nc.gov Hi Bob, and thanks for your email. I have itemized the Corps' responses below: Assumption 1: Yes, limiting the as -built topographic data to the fill removal area and roughly 10 to 15 feet outside of the limits of the fill removal limits should be fine, as long as that "area roughly 10 to 15 feet outside of the limits of the fill removal limits" is representative of the natural pond bottom prior to the unpermitted fill. Assumptions/Actions 2 and 3: The Corps concurs. Would it be possible for you to provide pictures of the pond bottom where the unpermitted fill has been removed? Thanks -Dave Bailey David E.

From: Bob Zarzecki <bzarzecki@sandec.com> Sent: Thursday, October 15, 2020 9:37 AM To: Bailey, David E CIV USARMY CESAW (USA) <David.E.Bailey2@usace.army.mil>; sue.homewood@ncdenr.gov Cc: Pete Goria <petegorial@gmail.com>; Alex Elkan <AELKAN@brookspierce.com>; Patrick Smith <psmith@sandec.com>; Allan Hill <ahill@triad-designgroup.com> Subject: [Non-DoD Source] Nationwide Permit 39 (After -the -Fact); McConnell Center - Lot 9, McLeansville, Guilford County; SAW-2018-02038 - WETLANDS MONITORING (S&EC 13795) David & Sue: On behalf of the permittee, we are providing you a brief update on this project. The permit approvals for this project included conditions that restoration work (removal of fill from the approximately 1.58-acre area pond bottom, etc.) was to "be completed within 120 days of receipt of all necessary federal, state and local approvals/permits". The DWR approval was dated April 13, 2020 and the USACE approval was dated April 21, 2020. The permitted work required a modification of the DEMLR erosion and sedimentation control (ESC) plan. This permit modification approval was received on August 25, 2020 (copy attached). As of today, the non -permitted fill has been removed from the pond bottom. The fill was removed to the extent and depth of the original pond bottom which was identified in part by the evidence of stumps, soil color, and other indicators of a drained pond bottom, along with the estimated elevation identified within the permit documents. The next step will be to breach the pond dam and stabilize the entire area (seed and mulch). The project engineer is coordinating the dam breach with DEMLR staff. Any potential changes to the breach plan provided in the permit documents will be provided to the USACE and DWR. DEMLR may be reaching out to DWR to ensure the sequencing of the dam breach is acceptable. We provide the follow assumptions/actions and ask for your confirmation of them. 1. Regarding the as -built, we understand that the USACE is looking for "...an as -built survey to ensure that target elevations were met, including comparisons with elevations of those areas within the pond bottom that were not filled or graded." We are assuming that the permittee will only need to survey the approximate red boundary shown on the attached drawing and that they don't need to survey the entire pond bed. This would include getting topographic data roughly 10 to 15 feet outside of the limits of the fill removal limits shown on the attached drawing. Please confirm this assumption is correct. 2. We assume that this as -built survey does not need to extend down to the dam and can be truncated to only show the area upstream (to the west) of the dashed orange line on the attached drawing. Please confirm that our understanding is correct. 3. The site contractor has recommended the application of a temporary seed mix (contractor grass seed blend, e.g., rye, etc.) at the same time that the wetland seed mix is applied and mulched. This is consistent with other wetland restoration efforts that S&EC has done in the past to ensure a quick stabilization of the area prior to the emergence of the wetland species. Please confirm that this is acceptable to the USACE and DWR. Please contact me if you have any questions or would like to visit the site.
